I recently needed to reset the password on an HPE MSA2040 SAN to which I had physical access. It turns out this information was more difficult to find than I had presumed.
The often recommended action is to contact HPE who will send a engineer on-site to reset the MSA password/settings. Don’t hesitate to do that if you have an active support contract. However, here are the instructions for doing it yourself, without a call to support:
- Connect to the MSA CLI interface over the USB serial port using putty, minicom or your preferred serial terminal emulator (see HPE documentation).
- Hit enter to display to the MSA welcome banner and login prompt
- Proceed to login with username
restoredefaultsand the serial number of the MSA module as the password
- The controller will reboot to factory settings, albeit retaining the network (IP) configuration
- Once the controller has rebooted, you can login with HPE default username
